Jfet pinch voltage question

    i thought that as we increase the voltage the gap becomes smaller
    and in pinch voltage we have an open circuit

    but the grath says otherwise
    that as we increase the voltage the current increases and in the pinch voltage (when there is no way for the electrons to move and we have a total deplition region on one side)
    we have a saturation
    and there is no decrease in current no where
    why?
